Isaac weakened to a tropical storm Wednesday afternoon while spinning slowly to the west-northwest over southern Louisiana. Since Isaac is moving at a snail's pace, the storm will continue to produce significant impacts along the northern Gulf Coast including storm surge flooding, heavy rainfall, strong winds and possible isolated tornadoes through Thursday.

Friday through the weekend ahead, Isaac's remnants will spin out of the South and into the Midwest. You can find a detailed look at the timing and impacts at this link.

Projected Path

Storm surge- Dangerous storm surge will persist through Wednesday night along the southeast Louisiana and Mississippi coasts. A storm surge of 10.9 feet above normal tide levels was reported at Shell Beach, La. to the southeast of New Orleans. In Waveland, Miss., a storm surge of 8 feet above normal tide levels was recorded.

Flooding rains- Isaac's slow movement will result in widespread rainfall amounts of 6 to 12 inches in eastern/central Louisiana, southeastern/central Arkansas and the southwestern half of Mississippi. Along and to either side of the Mississippi/Louisiana border, storm totals of 12 to 24 inches are possible; some locations could see historic rainfall amounts of up to 30 inches. Flooding is occurring across much of the region.

Power Outage Potential

Power outages- The long duration of strong winds has already knocked out power to hundreds of thousands. Additional power outages are possible into Thursday until Isaac's winds finally slacken. Power outages could last for days in some areas.
Tornadoes- Isolated tornadoes will continue to be possible in parts of southeast Louisiana, southern Mississippi and southwest Alabama through Wednesday night. Thursday, the threat of isolated tornadoes will expand to include much of Mississippi, western Alabama, eastern Louisiana and a large portion of Arkansas.
